RE: Commit & Logic cycle

No sure how many would remember a product call Baby34

It provided a RPG environment on a PC back in the late 70's I think.

But that was a bug we found that it would allow an update without prior
read and was causing data corruption and it took a lot of searching to
find and then prove the situation.

Oh the good old days ... NOT!

Cheers

Don

Wouldn't you get an "Update without prior read or chain"?

My first boss said he'd fire someone if a customer called reporting that
error....

S/38 and he vigorously promoted NOT using the cycle.

No. Exception output was always available and allowed sloppy programmers
to do crazy stuff, like reading a record once and updating it multiple
times without additional reads.

Logic cycle was on the System/3--I was on them all except for the

On the System/32, System/34, System/36 (which I avoided), and on the
System/38 as well. The logic cycle is a unique (AFAIK) of the

language

and

was on mainframe and HP(?) versions as well.

The question was: Was there ever *only* a logic cycle?

:wq! PoC
